Israeli Prime Minister Binyamin Netanyahu says his government will not agree to return Israel to the borders it held before 1967's Six Day War.

In a speech to pro-Israel lobbyists for the American-Israel Public Affairs Committee (AIPAC) in Washington on May 23, Netanyahu repeated his position that such territorial lines are "indefensible" for current-day Israel. He said he would make this clear in a speech to the U.S. Congress on May 24.

"Tomorrow, in Congress, I will describe what a peace between a Palestinian state and the Jewish state could look like," Netanyahu said. "But I want to assure you of one thing: It must leave Israel with security, and therefore Israel cannot return to the indefensible 1967 lines."

Last week, U.S. President Barack Obama said that future border negotiations between Israel and the Palestinians should be based on the territorial lines in place before Israel captured the West Bank, east Jerusalem, and the Gaza Strip in the the 1967 Arab-Israeli war. But Obama also said those lines could be adjusted if the Israelis and Palestinians agree to land exchanges.

The United States, Israel's ally, has been pushing to get the Israelis and Palestinians to resume substantive talks toward a peace settlement.
